SPECIFICATION formingpart of Letters Patent No. 289,688, dated December 4, 1883. Application filed March 14, 1883. (N0 model.)

{[0 all whom it may concern:

- Be it known that I, J ornv W. MORRISON, of Omaha, in the county of Douglas and State of Nebraska, have invented .unew and Improved Machine for Wetting Paper, of which the following is a full, clear, and exact description.

My improvements relate to machines for wetting paper in quires or quantity preparatory to printing; and the invention consists in certain novel features of construction and arrangement, having the object to place the work entirely under control of the operator, and also to facilitate the work, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the machine. Fig. Figs. 4 clutch 3 is an end elevation of the machine. and 5 are detail views of the cam and mechanism.

A is a tank for containing water, supported at a suitable height on standards a a.

b b are feed-rollers supported across one end or side of the tank by suitable hearings on standards a, the boxes b of the upper roller being fitted to slide, and held down by springs.

c c are the discharge-rollers, similarly fitted at the opposite end or side of the tank, the up per roller 0 having a sliding bearing, a. Each pair of rollers b b and c c are geared together. The lower roller b is rotated by gearing direct from a gear-wheel, d, on the main shaft e, and the lower roller 0 by a shaft, (1, connected by beveled gears c to said roller, and connected at its other end by a bevel-pinion, 6, to bevel-cogs on the side of wheel (I.

f f f are guide-rollers within the tank, for endless cords or belts 7, that pass, one set from upper roller b to upper roller 0, and the other cords from lower roller 1) to lower roller 0, both sets of cords passing over rollers f and beneath roller f, which is lowest in the tank, but always above the water-level.

g g are rollers at the bottom of the tank, for retaining the under side of the lower cords out of the Way.

h is a pan, preferably of concave f r-m, hung -rying beneath roller f, on the end of a lever, i, that is fulcrumed on a post, h.

c" is a hinged flap-valve in the bottom of the pan, opening upward to allow the pan to fill as it drops in the water.

5 k is a rod connected to the end of lever a, that extends outside the tank, and extending to shaft 6, where the end of rod is is slotted to stride the shaft.

Z is a cam loose on shaft 0.

l is a pin on rod is, extending over the cam, as shown in Fig. 4.

m is a sliding clutch mounted on the shaft, and fitted for movement, as shown most clearly in Fig. 5, for connection to and disconnection from cam Z.

m is a lever, hung on the under side of tank A, for moving the clutch, whereby when the clutch is moved to engage the cam the latter is rotated by the shaft and the pan it raised and lowered once at each revolution of the shaft. Lever i has a number of holes at varying distances from the fulcrum, so that the pin connecting rod to the lever can be set in and out to vary the throw or movement of the pan. These parts constitute the mechanism for earthe paper through the tank and wetting it. The feed and delivery mechanism is as follows:

n is atable fixed on the upper ends of standards a, for holding the stock of paper.

0 is an inclined table fixed on one side of tank A, in front of rollers b I).

a are side gages, adjustable on table 0, for guiding the paper.

p p are feed-fingers projecting through slots in table 0 from a rock-shaft, 0, which is mounted in bearings beneath the table.

is a crank-arm on shaft 0.

q is a pivoted arm at the side of the ma chine, hung on the upper end of a rod, 0', that is fitted to slide vertically in a guide, 1, and is further held in place by its lower end striding the main shaft 0.

q is a rod connecting the crank-arm p and arm q.

s is a cam on shaft (2, arranged to act 011 a pin, 8, projecting from rod 0', so as to raise and hold up the rod for a time at each revolution of the shaft.

tis a cam or projection on shaft of upper roller for taking against the upper end of arm q, or against a projection therefrom, for the purpose of moving the arm, and with it the fingers p, by the connections described. Both arms 1) q, connected by red q, have several holes to allow adjustment of the pin connecting rod q, so as to vary the extent of movement, and the rod is made in two pieces connected by a turn-buckle, q, so that the parts may be properly positioned.

At the opposite end of tank A is fixed a guard of curved wires, u, extending down from v the delivery-point of roller 0, and a rockshaft, at, extending transversely above the wires it, carries curved arms '1), which in their normal position lie close to the fixed wires, with space between for the paper to enter. A rod, 0, connects anarm, 'w, on shaft a to the pivoted arm q, so that the shaft is rocked simultaneously with the movement of feedfingers p, and the arms 11 thus swung out as the fingers 1) move inward. The rollers e are grooved to receive the fixed guards (Z which are placed at intervals in the length of the rollers, to prevent the wet paper from adhering to and winding on the rollers. At the delivery end, beneath guards at, is a table, a", Supported at its ends by slide-racks Z)", that engage cogged segments on the ends of weighted levers 0, so that the table is held up close to the guards when empty, and descends as the weight of paper increases on it, thus preventing disarrangement of the sheets by a fall to any distance. The main shaft eis to be rotated by connection to a prime mover.

In operation, a quire of paper is laid on table v0, in front of fingers p. The fingers then moving forward, the forward edge of the paper is thereby pushed between rollers b, and the paper is carried beneath roller f by cords 9. At the same time the pan h rising and being held up until the paper has passed, the water is brought into contact with the paper to-wet the under sheets only, or to submerge the whole, according to the adjustment. The paper, continuing to move by the cord, is carried out by rollers c, and as soon as the whole is received between the fixed guards u and arms 0 the latter swing out' and the paper drops upon the table. At the same moment another quire is moved forward by feed-fingers p. The delivery-rolls c squeeze the surplus water from the paper passing between them.

In case it is required to wet only alternate quires or lots, the lever m will be moved to disengage clutch m from cam Z, so that the pan h will not be raised to wet the paper passing through, and the clutch engaged again for the next lot, and so on, thereby causing the deposit on the table a of dry paper between every two wet quires.

It will be seen that the extent of the wetting tions may be arranged as found most desirable, and the delivery-fingers are to be made adjustable to suit different sizes of paper.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Iatent 1. I11 paper-wetting machines, the combination, with water-tanlc'A and endless cords or belts for carrying the paper, of the pan h, arranged for movement to and from the belts, substantially as shown and described.

2. In paperqvetting machines, the combination of rollers I) b c 0, bolts g, guidc-roll f, and pan h, fitted for movement to and from the guide-roll, substantially as described.

3. In paper-wetting machines, the pan 71' and lover 'Z, combined with tank A and the paper-carrying cords, substantially as shown and described.

4. In paper-wetting machines, the combination of water-pan h, lever Z, red It, cam Z, and shaft a, substantially as described, for operation as specified.

5. The combination, with the lever Z, carrying the bottom valved pan, h, of the slotted rod it, having pin Z, the shaft a, carrying loose cam Z, and the clutch mechanism at m, where by the pan may be raised or lowered, as described.

6. lhe combination, with feed-rolls b b, of which the upper one carries a cam, t, on its shaft, of the inclined slotted table 0, the side gages, a, the rock-shalt 0, having crank-arm 1) and feed-fingers p, the slide-rod 1-, having pin .9 and pivoted arm q, the rod q, connecting the arms 1) q, and the shaft 0, having cam s, as and for the purpose specified.

7. The combination, with the rolls 0 c, of the fixed curved guard-wires a, the transverse rock-shaft a, carrying curved arm 0, the sliderod 1', having pivoted arm q, and the rod 1:, connecting arms (1 '10, as and for the purpose specified.

8. In paper-wetting machines, the combination, with delivery-rollers, of guards at and vibrating arms 12, substantially as shown and described.
